I've been trying to play this for several days now. I like the concept and the feel of the game, but the server instability is a bummer. I also think a few additional quests/mobs would be helpful in relieving some of the congestion and 'grindyness'. Specifically, another quest before the departure from noob island, and also another quest in addition to the killer tomato and dirt spider quests. Alternatively, you could lower the level requirement for the yellow slime quest. They're easier to kill then the level 12 dirt spiders ;)
It also looks like my character has been deleted in the last 5 hours : ( It was fun while it lasted, but I don't think I'll restart.
